Earliest MLB Debuts

Quick question: Which active MLB player had the earliest debut game? Mariano Rivera? Derek Jeter? Jason Giambi?  They're close, but the player who beats them out by a matter of weeks is LaTroy Hawkins, presently of the Mets and formerly of the Angels, Brewers, Astros, Yankees, Rockies, Orioles, Giants, Cubs, and Twins.  He made his MLB debut on April 29, 1995, a mere 9 days before the runner-up, Mariano Rivera.

Now, 1995 seems like it wasn't all that long ago, especially when considering that last year's leader, Jamie Moyer, first started playing in the majors in 1986.  So, I decided to take a look at, historically, who among active layers in each season had the earliest debuts.  As my discoveries showed, it is in fact unusual to have no active players from 20 years ago or earlier - in fact, unless someone like Jamie Moyer or Omar Vizquel makes another appearance before the end of this year, it will be the first time since 1969 that the longest-active player debuted 18 years prior.  The leader in that season? Willie Mays, who debuted in 1951.

So, I have included the list, showing which player in each season had the earliest debut, going back to 1894. Note that I am not counting the National Association (1871-1875) as a major league, so players such as Jim O'Rourke and Cap Anson are listed here as having their MLB debuts in 1876, rather than basing it on their first year in the NA.
